From the baseballr package

batting_orders <- map_dfr(games, get_batting_orders)

So the games is a vector for every unique game, and I was wondering if I could attach each game ID that I'm giving as an input in map_dfr, to the outputting dataframe.

I tried to create a function, but it wont take a vector as an input.

Yes, map_dfr has an argument for it: .id; you just have to give an name and the input value is automatically added to your data.frame:

batting_orders <- map_dfr(games, get_batting_orders, .id = "game_id")
